I made the planets take shortcuts (linear hops) by increasing the simulation speed by 10 Maybe you could speed it up by removing the massive output in the extra window and display that info in the main screen?

I heard that one of our planets doesn't patrol on the same 'disc' like all of our other planets, did you thake that into account?

I never realized that the outer planets are located so far away from earth. So I guess, chances to send a manned spacecraft to one of the outer planets are 0.0. (Unless some rocket scienctists invent a warp drive ).
